CALENDER-ROL LER.

SPECIFICATION forming part of Letters Patent No. 700,338, dated May20, 1'902.' I V Application filed February s, 1901. Serial in, 47,845.

To all whont it may concern:

Be it known that I, J OHANNES KLEINEWEF- ERS, manufacturer, a subject of the King of Prussia, Emperor of Germany, residing at Orefeld, Rhenish Prussia, in the German Emveniences are avoided by the calender-rollers forming the subject of this invention, where a far higher degree of resistibility is produced,

and therefore the rollers rendered more durable, by manufacturing the outer covering of the same of a combination of different kinds of' materialr r In the accompanying drawing I have shown by Way of example part of an improved cal-.j

' composed being, however, shownfor the sake,

of illustration on a greatly-enlarged scale.

ender-roller as constructed in accordance with my invention, the thickness of the several layers of material of which the covering is The outer covering of such rollers is composed of several layers or disks in the wellknown manner, which are attached in any suitable manner upon the mandrel a of the roller.

The outer covering, formiug the operative surface of my improved roller, is made up of disks of paper b,silk tissue 'c',or cotton fabric d, or other similar material, as jute orthe like. The disks of these several kinds ofmaterialare alternating with each other. They may otherwise be differentlyarranged upon the mandrel of the roller. I may either arrange series of alternating paper,silk, and cotton disks in succession, or I mayreversethe order of the disks I of paper, forinstance,alternate with'a layer g 1 .ofloosethreads of another material' fsuch as 1 4 cotton; si lk,. or te-ihreaqs; so--asmhave some of the layers of.the'combinationlconsist.

in some of the series, or I may combine several disks of the same material upon which is placed the same number of disks of another material, or I may have unequal numbers-of disks of each material alternate with each I other, thereby producing layers of different thickness. In short, the manner of composing orcombining together the different layers 5 5 is immaterial aslong as layers of different material are alternating with each other upon the mandrehnor .is it indispensable tov use always full soliddiskso'f thematerial intjques tion. ThusI ma'yarra'ng'e to have full'disks 6o 1 of single loosethr'eadsinstead offabrics.

The roller is then finished by smoothening the outer suri a face of the covering. I 1 i What I claim, anddesire tos'ecure by Letters Patent ofthe United States, is--- 1.
